MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 367,340, dated July 26, 1887.

i Apnlication filed November 8, 1886. Serial No. 218,329. -(No model.) I d To all whom it may concern:

Be it known that I, ROBERT F. FLEAK, a citizen of the United States of America, and resident of Stuart, in the county of Guthrie and State of Iowa, have invented a new and useful Mechanical Movement, of which the following is a specification.

My object is to produce intermittent rotary motions in reverse ways by means of a continuous rotary motion, and Iaccomplish the same by the construction and combination of a'shaft having a groove or flange on its periphery, a frame adapted to support the grooved shaft, a sliding cross-piece having, a fixed pin, and a crank-shaft, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is aside view, Fig. 2 a top view, and Fig. 3 a perspective view,of my complete device. Fig. 4 shows a flange on the shaft eX- tended in reverse ways from a straight vertical section in, the center. Fig. 5 shows aflange in serpentine form.

A is the frame, preferably made of cast 2 metal and adapted to be fixed on the cover of a churn. It has'a lateral extension, B, at its top, that serves as a bearer to support the rotating grooved or flanged shaft.

0 are bearers formed on or fixed to the base 5: to support the crank-shaft in a right-angled position to the grooved or flanged shaft.

N0. 1 is a grooved shaft and No. 2 the crankshaft.

(l is a groove formed in the surface of the shaft No. 1, or fixed thereto in any suitable way. f

F represents a dr ing-wheel fixed to the end of the crank-shaft No. 2.

g is a wrist-pin fixed to the crank h'of the o shaft No. 2.

I m is a cross-bar that slides up and down in grooves in the frame. A pin, n, fixed to this cross-bar projects into the groove (1 of the shaft No. 1, and the pin g on the end of the crank h projects into a slot, 1", in the crossbar, as clearly shown in Fig. 3, which slot it traverses when the device is in operation.

When the wheel F is rotated by hand, or power applied in any other way, the crank on the end of the shaft No. 2 will slide the pin 9 back and forth in the slot r of the crossbar m, and thereby move said cross-bar up and down in its bearings and cause the pin a to traverse the groove din the shaft No. l, as required to perform the function ofa cam in imparting a rotary motion to that shaft. moves in reverseways in the straight slot in the cross-bar m, the rotary motion of the shaft No. 1 will also be in reverse ways as required to operate a churn-dasher attached to the lower end of the shaft, or other operative device that may be substituted for the dasher.

The number of revolutions or the fractional parts of a revolution of the No. 1 shaft will be governed by the form of the-groove d, which may be a regular spiral curve, as shown in Fig. 1, or provided with one or more straight sections, as shown in Fig. 4, or serpentine bends, as shown in Fig. 5.

I claim as my invention-- 1. The combination of a straight shaft or cylinder having a groove on its periphery, a shaft having a crank on its end in a rightaugled position to the grooved shaft, a wrist-pin on the end of the crank, asliding cross-bar having a pin projecting into the groove in the shaft, and a frame or base having bearings to support the two shafts, to operate in the manner set forth.

2. The frame A B O, the rotating shaft N0. 1, having a groove, d, the shaft N 0. 2, the

As the pin 9' driving-wheel F, having a crank, h, the pin 9,

and the sliding bar at, having a slot, 1, and a pin, 12, arranged and combined to operate in the manner set 'forth. 7

ROBERT F. FLEAK.
